Phone Home
----------
**Summary:** post data to url

This module can be used to post data to a remote host after boot is complete.
If the post url contains the string ``$INSTANCE_ID`` it will be replaced with
the id of the current instance. Either all data can be posted or a list of
keys to post. Available keys are:

- ``pub_key_dsa``
    - ``pub_key_rsa``
    - ``pub_key_ecdsa``
    - ``pub_key_ed25519``
    - ``instance_id``
    - ``hostname``
    - ``fdqn``

**Internal name:** ``cc_phone_home``

**Module frequency:** per instance

**Supported distros:** all

**Config keys**::

phone_home:
        url: http://example.com/$INSTANCE_ID/
        post:
            - pub_key_dsa
            - instance_id
            - fqdn
        tries: 10
